Unhappy 2007 GT electronics reset problem

For the first time, today all of my electronics seem to reset while I was driving down the road.
The car hesitated for a second, all the dashboard warning lights came on and went off (kind of like at startup), and the trip counter switched back total miles.
The first time this happened I was turning on the lights - I turned them back off to be cautious. A few minutes later, the exact same thing happened again, but this time I didn't do anything that could have initiated it. Then when I got to my destination and got out of the car, the door was hard to close because the window didn't do that automatic little down up it does.
When I got back in the car to drive home, the radio had reset back to AM and the time changed to the wrong time.
As I drove back home I encountered no more issues - all seemed normal.

I have never had the behavior before - any ideas?

Check your electrical connections and from the PCM. Then check your Battery terminals. You might even want to disconnect them both clean them and tighten them back down.

How old is your battery? It could be on its last leg and getting ready to die.

Your electrical system is flickering. Maybe a loose battery connection, a failing battery/charging system, or it maybe an ECU malfunction. Try reflashing your system with the same tune if you can, but I would start out by disconnecting the battery and doing a hard reset of all the electrical systems. But just remember that if the problem consists, really try and find the exact cause, because one time the systems might go off and not come back on, then you've got a very fun scenario, since all of the systems are fly-by-wire (run by the electrical system). But it sounds like a loose connection close to the battery, an ECU malfunction, or a failing battery or charging system. And also, don't trust the gauges on your dash except for maybe the temperature sensor, since the secondary motors that drive the needles in the small gauges are notorious for malfunctions, and can read the same whether your battery is dead or new in some cases.
